The device files should be created by udev automatically when you
pluging the device, or boot the PC.. When you un/plug the device you
should see some info in dmesg. Perhaps you have some kind of error
occurring. you could try rmmod "ehci_hcd" to try using USB 1.1 instead
of usb 2.0. You could also try plugging it into a different hub or usb
port on the PC.

I'd run a tail -f on /var/log/messages (or wherever your kernel messages go) so you can see what's happening as you plug / unplug the device. In Gentoo, the default for syslog-ng is to have it default log to tty12 so you can just flip over there.
